Abstract

本实用新型涉及一种带有扬料板的滚筒式初清筛,用于对谷物进行清理、除杂和分选,包括滚筒结构的筛体,其特征在于:筛体内设置有多个扬料板,扬料板倾斜设置,扬料板底部与筛体内壁之间的间距为30mm~80mm,扬料板底部通过支撑杆固定在筛体的内壁上。带有扬料板的滚筒式初清筛通过在筛体内增设了扬料板,当筛体顺时针旋转时,原本应该集中在筛体左下部的谷物,会分为两部分,低于扬料板的谷物会继续留在左下部进行筛选,处于扬料板上的谷物,会被扬料板扬起,散落到筛体的右侧进行筛选,使得筛体的有效筛面比现有的初清筛增加了近一倍,提高了工作效率。

Description

带有扬料板的滚筒式初清筛
技术领域
本实用新型涉及一种带有扬料板的滚筒式初清筛,用于对谷物进行清理、除杂和分选。
背景技术
目前,现有滚筒式清理筛当筛体转动时,筛体的有效面积不大,假设筛体按顺时针方向旋转,那么谷物会集中筛体的左下部分,筛体的有效面只有四分之一不到,这样便限制了初清筛的产量。
实用新型内容
根据以上现有技术中的不足,本实用新型要解决的技术问题是:提供一种解决了上述缺陷的,增大了筛体的有效筛面的带有扬料板的滚筒式初清筛。
本实用新型解决其技术问题所采用的技术方案是:所述的带有扬料板的滚筒式初清筛,包括滚筒结构的筛体,其特征在于:筛体内设置有多个扬料板,扬料板倾斜设置,扬料板底部与筛体内壁之间的间距为30mm~80mm,扬料板底部通过支撑杆固定在筛体的内壁上。
所述的扬料板与筛体的法线之间的夹角为25~35°。优选为30°。
所述的扬料板的数量为5~15个。扬料板的数量根据筛体的直径需要而设定。
所述的扬料板均匀分布。
所述的扬料板底部通过2~6根支撑杆固定在筛体的内壁上。支撑杆的数量是按筛体的长度及支撑强度而设定的。
本实用新型所具有的有益效果是:带有扬料板的滚筒式初清筛通过在筛体内增设了扬料板,当筛体顺时针旋转时,原本应该集中在筛体左下部的谷物,会分为两部分,低于扬料板的谷物会继续留在左下部进行筛选,处于扬料板上的谷物,会被扬料板扬起,散落到筛体的右侧进行筛选,使得筛体的有效筛面比现有的初清筛增加了近一倍,提高了工作效率。
附图说明
图1是本实用新型的结构示意图;
图2是图1的A-A剖视图。
图中:1、筛体;2、扬料板;3、支撑杆。
具体实施方式
下面结合附图对本实用新型的实施例做进一步描述:
如图1~2所示,筛体1内设置有多个扬料板2,扬料板2倾斜设置,扬料板2底部与筛体1内壁之间的间距为30mm~80mm,扬料板2底部通过支撑杆3固定在筛体1的内壁上。
扬料板2与筛体1的法线之间的夹角为25~35°,扬料板2的数量为12个,扬料板2均匀分布,扬料板2底部通过4根支撑杆3固定在筛体1的内壁上,扬料板2的长度与筛体1的长度相适应。
当筛体1顺时针旋转时,原本应该集中在筛体1左下部的谷物,会分为两部分,低于扬料板2的谷物会继续留在左下部进行筛选,处于扬料板2上的谷物,会被扬料板2扬起,散落到筛体1的右侧进行筛选,使得筛体1的有效筛面比现有的初清筛增加了近一倍,提高了工作效率。
